Abstract

Election issues are sensitive information among the society because they relate to people's survival in terms of work, economy and education. Election hoaxes where information whose truth cannot be ascertained becomes a weapon used by certain parties to bring down political opponents. Social media such as TikTok is a media that is often used to spread hoaxes because TikTok social media users come from various ages and there is no distance or time between users. In this paper, a mathematical model is presented to see how the equilibrium point is to be free from hoax based on the basic reproduction number R0. The spread of hoaxes on social media occurs if R0 > 1 and does not occur if R0 < 1. The model approach used is the SEIR mathematical model because it is seen that there are people who receive hoax videos (exposed) and then spread them without finding out the truth (infected), and users with this condition it needs to be recovered. The method used in this research is a literature review. The results obtained show that the mathematical model presented shows that the basic reproduction number R0 is zero (R0 < 1). This means that there will be no spread of election hoaxes

Abstract

Shredder machines are classified as cutting machines that use two types of rolls, namely feed rolls and shredder rolls. First the sheet will be inserted, then the feed roll will wrap around the rubber sheet which is pulled into the machine at the same time as the feed roll which wraps around the rubber sheet. Then the thread on the main roll plays the role of pulling the rubber sheet and also the solid corner of the main roll thread also acts as a knife which will press the rubber sheet together with the Death Knife which will clamp the rubber sheet until the rubber sheet is broken or cut. The events that occur in the process of cutting rubber sheets on the shredder machine are the occurrence of cutting forces between the interaction of angles on the main roll thread and also the death knife. This research uses observation and interview methods to collect this data. From the research results, it was concluded that the amount of cutting force required by the cutting knife to cut rubber into small pieces was 247,242 N. Meanwhile, the amount of power used to produce the cutting force to cut rubber sheets was 2,651 HP.

Abstract

Forklift is one of the means of transportation used in PT ABC. PT ABC is the first company to produce fish oil and flour using whole fish as raw material. Wear on engine components is a problem that is often faced in industry, especially in heavy equipment such as forklifts. One component that experiences significant wear is the double clutch, which functions as a connection between the engine and transmission in the clutch system. One of the main causes of wear on the double clutch is friction that occurs with the clutch cover (clutch sun). This study aims to determine the amount of wear volume that occurs on the double clutch and to determine the amount of wear rate that occurs on the double clutch. The method used in this study is data analysis. From the results of the study, it can be concluded that the Wear Volume that occurs on the double clutch is 7.1053 x 10-4 mm3 and the Wear Rate that occurs on the double clutch is 2.13624343 x 10-18 g / sec.mm2.
